Application f11ed`0ctober 16, 1922. SerialgNo. 594,885.

This invention krelates to receptaclesfor liquids and particularly to receptacles that` are provided with means for positively discharging liquidsV therefrom. c

Receptacles have heretofore been provided with means for positively ejecting they contained liquids, said means comprising av the operating mechanism of the pump, with the result that said valve has ceased to func- Y tion after a relatively short period of use.

Furthermore these types of discharge means have had a very limited capacity as regards the quantity of liquid that can be discharged Vat a single stroke, and have also been expensive to manufacture.

These and other undesirable features have proven by experience to 'be so objectionable that the sale of receptacles of thischaracter is `decreasing although the demand for a satisfactory receptacle of this type is increasing.

One of the objects of the .present invention is to provide a receptacle of theabove t-ype which has a positively actuated intak valve. 1

Another `object of this vinvention 4is to pro.- vide pumping means comprising an expansible and collapsible vessel which mayv be reciprocated, whereby, through a portion of its movement., said vessel moves as a whole as distinguished from the previous practice of having one end wall of the vessel station'- ary while the other end wall alone Yis movable. I

A further objectof thisv inventionis to provide novel means for attaching. the end walls of the collapsible and expansible vessel to the flexible-side wallthereof,wheijeby the necessity of solder for sealing this joint is avoided, and the cost of manufacture materially reduced. These and other objects will appear as then-description proceeds. 1

The invention is capable of receiving a variety of mechanical expressions, several of which for purposes of illustration are shown in the accompanying drawings, butit is to be expressly understood thatthe drawings are for purposes of illustration only, and are not to be construed as definitive of the limits of the invention, reference ybeing had to the vappended claims for that purpose.

' Fig. 12 is an elevation, partly in section,

' of another embodiment of the invention, the

lower portions of the receptacle and pumping means being. omitted.

1n the form shown in Fig. 1, wherein is illustrated a receptacle or oil can of the type known in the art as pump type Oilers used for oiling large machinery, shaft bearings, locomotives., etc., the main bodyportion orshell of thereceptacle, whichV may be of any suitable construction, material. size, etc., comprises anfupper portionl fitted and secured to alower portion2 by means of a joint 3, which joint. may besealed by solder or electric welding. A handle 4 of the usual type is attachedv to these portions in'any suitable manner as'by solder or spot welding. A ferrule' 5secured to upper pore tion 1 by means of a soldered flange 6 and provided with a threaded cap 7 affords the usual filling aperture.

Any suitable means affording a discharge opening may be provided in upper portion 1.` 1n the illustrated embodiment, a flanged and threaded member 8 extends through an opening 9 in portion 1, and is secured in n bonnet 18 is a stuffing gland 2() filled with a` place by means of a lock nut 10. A spout 11 of any desired length and provided at the lower end thereof with a flange 12 is secured to the upper end of member 8 by means of theinteriorly-threaded flanged nut 13. Attached in any suitable 'manner to the lower end of member 8, and interiorly thereof, is the discharge pipe 14 which will be more fully described hereinafter. To ensure that oil or other contained liquid will not escape from the receptacle when the latter is in other than the uprightl position, a check valve 15 having a seat in the upper end of pipe 14, is preferably mounted within the recess in member 8. A compression spring 16, bearing at one end against member 8 and yat its opposite end against a flange formed on valve 15, normally maintains the latter in seated position. In order that any surplus oil that remains in spout 11 after an oiling operation may drain back into the receptacle a small hole 17 is preferably provided in valve 15. The above discharge means need not be located in the center of portionvl, for if desired it can be placed in any other suitable position.`

In order that thev liquid contained in the receptacle may be positively discharged, I have provided the following means: Secured to portion 1 of the shell of the receptacle, adjacent the upper end of handle 4, is the interiorly extending bonnet 18 provided with the flanged portion 19 suitably secured to the shell as by solder. In the outer end of suitablev packing material 21Yheld in place by the usual packing nut 22. Slidably mounted in bonnet 18 is the shaft 23, carrying on its outer end theusual thumb but- Y ton 24, and suitably secured at its inner end to the upper, ire-entrant end wall 25 of an expaiisible and collapsible member 26. A. tension spring .27, surrounding shaft 23, preferably has its upper end screwed onto the lower threaded portion of bonnet 18 and its opposite end screwed onto an enlarged portion 28 of shaft23, said spring normally maintaining the shaft in such a position that. a collar 29 formed on the latter is abutting the lower end of bonnet 18.

The flexible corrugated .member 26 preferably made of resilient metal is provided with a lower end wall 30, having a flanged portion 31 and an opening 32, said flanged portion extending into a guide piece or abutment member 33 suitably secured to the lower end of discharge pipe 14 to provide 4an intake valve. The detailed construction of guide 33 is shown more clearly in Fig. 2 where it will be seen that it comprises a suitable number of widely spaced prongs 34 extending substantially at right'angles from'the base portion 35 to telescopically "receive and guide the reciprocating movement of the flanged portion 31 of end wall 30. Tube 14 preferably extends downward to, or near, the bottoni of the receptacle and has its extremity upturned, and guide 33, carrying leather gasket or washer 36, is suitably held in position on the end of said tube Vas by flanging over the end of pipe 14.

The rigid end walls 25 Vand 30 are-preferably secured to corrugated :member 26 as illustrated in Fig. 3, wherein wall 30 is shown as provided with a return bend 37 around its outer periphery and flexible mem- Y saving the cost of solder, which is a' material item, but likewise the labor involved in applying it. Y

The operation of the above described embodiment of the invention is as follows:V

The receptacle having been filled with oil or i other liquid through the opening provided in ferrule 5 and it being desired to discharge the oil from the container, handle 4vis securely held and by means of thumb pressure against button 24 shaft 23 is forced downwardly carrying with it end wall .25, flexible member 26 and end wall 30.' This movement continues until the flanged portion 31 of end wall 30 comes into contact with leather gasket 36 at which time lthe escape of oil between the flanged portion and the gasket is positively prevented. Up to this time there has been no material collapse of flexible member 26 but further downward inovcment of the shaftv23 and wall 25 causes member 26 to collapse owing to the fact'that the wall'30 cannot move further downward. The oil or contained liquid is thus forced into pipe 14 and check valve 15 is lifted allowing oil to pass out through thev spout 11. Gil is thus continually ejected from spout 11 until shaft 23 and end wall 25 have been moved downwardly to the point where the lowerv portion of wall 25'contacts with lower end wall 30,' whereupon thumb pressure is relieved from button 24. Spring 16 immediately seats valve 15 and prevents v oil being redrawn from spout 11 and at the same time spring 27 forces shaft 23 upward until collar 29 abuts against thebottom of bonnet 18. This movement of shaft 23, which results inthe expansion of 'member 26, cau-ses'the pressure within the collapsible and expansible member to drop below the pressure surrounding it, and the area of end wall 30 parallel to the corrugations of member 26 being purposely made larger than the areav of the flanged end 31 thereof, said wall will be lifted 'away from gasket 36 by thev unbalanced pressure, so that oil can pass 1nV between guide prongs 34 and upward through opening 32, thereby allowing flexible member 26 to expand by virtue of its resilience and to be refilled with oil drawn from the main reservoir of the receptacle. By. again pressing'thumb button 24 the opcan pass therethrough very slowly and when pressure is removed from button 24 there is no inrush of oil followed byair from spout 11 to prevent collapsible and expansible member 26 from becoming again filled with oil.

In F ig. 4 there is illustrated another embodiment of the inventive idea in which the receptacle is adapted to be used for the storage of oil, alcohol, turpentine and similar liquids. In the form -sh-owln'the body'or shell portion 39 of vthis receptacle is closed at its upper en d by wall 40 and its lower end by wall 41, the end walls being secured to the side walls by means of the seams'f42, 43 in any usual and well known way.r Upper wall 40 is provided with a filling aperture 44 similar to that previously described. Projecting through the upper wall 40 at any suitable point is the exteriorly threaded feri'ule provided with flange portion 46, the latter being suitably connected to wall 40 by rivets or solder.. Ferrule 45 is provided with stuffing gland 47 carrying a suitable packing material 48 held in position by nut 49. Extending through ferrule 45 is the slidably mounted discharge pipe 50 vcarrying on its lower threaded endl the cup-shaped member 51 having a bottom flanged lportion 52 attached to the re-entrant wall 53 o f the collapsible and expansible member 26a in any suitable way as by means of rivets`54.' Wall 53 is provided with an opening 55 concentric with the pip-e V50 and surrounding said opening there may be provided, if desired, an annular corrugation 56 which servesas the seat for a leather flap valve 57 secured e the lateral wall ofthe cup-shaped piece 51.` Immediately above `valve 57 vand at-j tached to the piece 5l'is a perforated metal guard 58 for a purpose to be hereinafter described. The construction Iof the valve 57 and guard 58 are shown more fully in Figs. 7 and 8. The lower end of expansible and collapsible member 26a is closed by a wall .guide prongs 64 .which terminate at their upper extremities in inwardly projecting arms 65. The construction of this guide is shown in ydetail in Figs. 9v and 10. In afssembling this portion of the yStructure which constitutes the intake valve, prongs 64 are firstmade straight and then thellange 61 of tubular portion on end wall 59 is insertedtherein and the 'inwardly projecting arms 65 are then bent over into position so thatV flangev portion 61 cannot thereafter be withdrawn from saidguide. A gasket 66 of anyy suitable material is mount-ed in the lower portion of guide 63 to serve as a seat against `which flange 61v will contact during the operation of the device. Attached to discharge pipe 50 is a split ring 67 which serves as a stop to limit the upward movement of said pipe. The preferred construction of this ring is shown in detail in Figs. 5 and 6 where it will be seen that anannular groove 68 is formed in the outer surface of pipe 50 and into this groove is Y sprung ring 67 which, as illustrated, is rectangular in cross section, the ends thereof abutting as at 69. Threaded on to the upper end of pipe 50 is a bushing 70 which-carries on its' upper end an L 71. A conical valve 72 provided with a threaded stem 73 and hand wheel74 is 4adapted to close the upper end of pipe 50 when engaged with the seat 75 formed in the upper end of bushing 70. A dischargenozzle 76 is threaded into the lateral arm of L 7 1 The operation of this embodiment of the invention is as follows:

VllVlienit is desired to dischargeliquid from the receptacle, valve 72 is moved to the open position as illustrated in Fig. 4 by turning hand wheel 74 until the upper surface of .said

valve abuts against the interior surface of L f 7l in which position.l it makes a fluid-tight joint with the inner surface of the L and prevents escape of fluid around the threaded stem 73. Hand wheel 74 is then pulled upward carrying with it discharge pipe 50, cupshaped member 51, wall 53, collapsible and expa'nsible member 26, and lower wall 59 until the 4flanged extension 61 of the latter contacts with the arms 65 of guide 63, whereupon lower wallf59 ceases to move upwardly.

Wall 53 however iscarried still further upward thereby expanding flexible member 26 until split ring 67 contacts with the4 ferrule 45. During this movement oil or any other conta-ined liquid is drawn into collapsible member 25a through the openings between f the prongs 64 and the tubular portion 60 of end wall 59. Also valve 57 is securely seated against corrugation 56 at the commencement of the upward movement of pipe 50 thereby eliectively sealing opening 55. Hand wheel 74rhaving been moved to its extreme limit of upward travel, it is now pressed downward until flanged extension 6l comes in contact with vwasher 66 to prevent further flow of liquid between these elements, whereupon the end wall 59 cannot move downwardly any further. and further pressure on hand wheel 74 collapses the flexible member 25a so that the liquid which has been drawn into this member 26, being unable to escape back int-o the interior or" the receptacle, forces valve 57 olf its seat, and passes up through discharge pipe 50 and discharge nozzle 76. Pressure on wheel .74 is continued until the lower part ofy the re-entrant wall 53 contacts with wall 59 whereupon wheel 74 is moved in the reverse direction and the operation repeated.

Guard 58 limits the amount of lift of valve 57 otherwise the latter might be opened so widely and its closing movement require so much time as to completely drain pipe 50 of liquid and allow air to enter the tank through opening 55. When there is liquid in the pipe 50 and wheel 74l is lifted liquid rushes through the perforations in guard 58 and immediately forces valve 57 back to its seat. VAfter the required amount of liquid has been discharged from the receptacle, conical valve 7 2 is screwed back onto its seat 75 to insure against any accidental discharge from the tank. It will be noted that the construction provided in this embodiment of the invention is such that discharge nozzle 75 may be turned 'in azimuth 360C" without impairing the operation of the pumping means. Valls 53 and 59 are preferably secured to collapsible member 26a byv means of a. lock seam suchas is illustrated in Fig. 3. A very small hole may be provided in the center of valve 57 to allow liquid which has accumulated in pipe 50 to drain back into the receptacle; however, this is not essential, and I prefer to omit it.

Experience has shown that when a receptacle is being` filled with liquid for the first time there is a tendency for air to be trapped in the' space 77 between re-entrant wall 53 and lcollapsible member 26a. This space is reduced to a minimum in the illustrated embodiment by having wall 53 fit very closely inside of member 26a and usually the small accumulation of air in this space is not objectionable. but when the kind of liquid being stored and the nature of service required makes it desirable to eliminate this air, an extremely small airhole'78may be rovided near the top of re-entrant wall 5,3 so that as the tank is being filled yair will escape out through this small hole. It will be readily understood that hole 78 is .so small that the' amount of liquid which can escape therethrough during the pumping action is negligible.

In Fig. l1 there is illustrated another embodiment showing pumping means which may be employed, wherein the outlet valve as well as the intake valve is positively open ated.. In this embodiment upper wall 53 of the expansible and collapsible vessel is provided with a. circular recess 79 in which is located a disk valve 80 carried on the lower threaded end of discharge pipe .50, said pipe, which is reduced in outside Vdiameter near the lower end thereof as at 8l, being slidably fittedy into an opening 82 in the top of wall 53. The bottom end of pipe 50 is closed as at 83 and any suitable number of openings 84 are provided in the side walls thereof Vimmediately above valve 80. Lower wall 59 of the collapsible and expansible vessel is preferably made re-entrant and the tubular inlet 60, provided with a flanged end 61, extends downwardly between the prongs 64C of a guide member such as has heretofore been described. It will be noted that in this embodiment of the invention the discharge valvek 8O is positively actuated during the pumping operation and is not dependent upon liquid pressure. The construction of lower wall 59 of the collapsible and fexpansible vessel is such that no appreciable amount of air can collect in said vessel when the receptacle is being filled and any air that may collect therein will be quickly discharged during the first Stroke of the pump.

In Fig. 12 is shown a still further embodiment of the inventive idea wherein the gland 47, packing 48 and nut 49 `of Fig. 4 (or the corresponding elements of Fig. l) are unnecessary in that a collapsible and 'expansibleY wall is employed to make this fluidtight joint. In ythe form illustrated, the upper rigid wall 86 of a flexible member 85 is securely held in position in end member e0 by means of the interiorly threaded nut 87, thus forming a fluid-tight joint. Lower end wall 88 of member 85 is provided with a hub or flanged portion 89 through which passes pipe 50, said hub being securely fastened to said pipe in any suitable manner to form a liquid tight joint. It will be noted that this construction does not permit of discharge member 76 being turned 1n azimuth, and7 in order to insure against undue torsional strain on flexible wall v when actuatingv hand wheel 74, guide '90 is provided in which nozzle- 76 slides vertically. Guide 90 comprises a U-shaped member which is secured to wall .l0 of the receptacle Vl. In. a"receptacleffor liquids, vthe combinat-ion of a casing, a member reciprocably' '.moimtedin said casing, and pumping means f securedto saidmember, said means includ- .embodiment illustrated in Fig. 4l.V v It Will be noted that the intake member of the various embodiments has been killustrated as having a greater inside diameter than the discharge or outlet pipe. VThis permits liquid to be taken into the collapsible and expansible vessel very quickly butit. can

he discharged only as fast as pressure is applied, thus giving the rpump the quick return stroke feature. It is to be understood however that the intake and outlet members maybe made the same size if desiredy.

While the several embodiments of the in- .vention illustrated on ,the drawings have been described 4with considerable particularity it is to be expressly understood that the invention :is not 4.to be restricted to the forms there shown since it is capableof` receiving a` Avariety of mechanical expressions -soiiie of. which Will now readily Y sug est themselves to those skilled in the art, Wille certain features thereof are `capableof use without. other features thereof. `-Reference is therefore to'be -had to the claims .hereto appended for a deiinition ofthe invention.
